Linux: Out-of-bounds Read
CVE-2024-53082 is a high-severity out-of-bounds read vulnerability in Linux, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions f3401e3c8d339ddb6ccb2e3d11ad634b7846a806, af0aa8aecbe8985079232902894cc4cb62795691, 6a18a783b1fa590ad1ed785907263e4b86adcfe2 as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.24% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Linux to f3401e3c8d339ddb6ccb2e3d11ad634b7846a806 or af0aa8aecbe8985079232902894cc4cb62795691 or 6a18a783b1fa590ad1ed785907263e4b86adcfe2 or 3f7d9c1964fcd16d02a8a9d4fd6f6cb60c4cc530, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.1.117 or 6.6.61 or 6.11.8, whichever matches your release line, or a later version.
